Navigating the Sidewalk Animation
Guide by John Allen, May 8, 2021
I developed this tutorial while viewing the video at https://cyclingsavvy.org/instructor_area/teaching-resources/classroom-presentation-guide. The video describes what the animation is intended to convey. This document will help you with the mouse clicks to navigate through it. Unless you have two computer monitors, you will want to print this out so it does not occupy space on your computer screen.
***************
- In Section 2 of the classroom presentation, click on Sidewalk Crashes (movie camera icon) to open the animation. Frame sidewalk riding as a personal choice. Note, if you close the main screen before closing the animation (any animation – which opens in a new window), you will lose all tabs, at least in Firefox, and they can be recovered only from the application data. So it is best to run the presentation in a browser which you don’t normally use, or to set up a user account on your computer where you can trash the browser cache, because you use the browser only to give the presentation.
- Click the pedestrian, lower left. Walk through speed differences. Ask how fast does a pedestrian go? How far from one driveway when one second away? Pedestrian is using a driveway: no obligation to stop.
- Click the 10 mph cyclist.
- Click the scooter, 15 mph.
- Click the e-bike, 20 mph. All one second away. Only those you have clicked on will show.
- Then click on 2.5s button at lower left to go to 2 1/2 seconds. This button will appear only after clicking on the e-bike. 2 1/2 seconds is the standard perception/reaction time and shows where each sidewalk user is at the time it is necessary to be aware of the hazard ahead — often well before that hazard develops.; also where the driver of the vehicle has to see the sidewalk user to react in time.
- “Now we move on to the crashes” – Click on square with arrows at lower right to reveal vehicles on road and sidewalk riders. Note green triangle at lower right. It will take you back to this step but if you have clicked on sidepath or cycle track, you can’t go back to sidewalk without quitting the animation.. So don’t click on those now.
- Click on 1, truck, right turns. Other vehicles disappear.
- Then click on the leftmost white arrow. Example is for 10 mph cyclists. Right hook with truck will show. The animation runs for four seconds, You may not see anything immediately.
- After animation plays, click on left orange square to back it up, then
- Click on the truck to show driver’s focus area. Discuss: looking into driveway, sidewalk near driveway.
- Then click on cyclist to show scan area.
- X button turns off focus areas (Optional? “You may.”)
- Click on middle white arrow to animate crash with cyclist on sidewalk facing traffic.
- Back up with second orange square. Click on truck again to show focus area.
- Click on bush icon at lower left at any time to plant bushes and instantly grow them to maturity.
- Click on cyclist to show cyclist’s scan area.
- Click on bushes (not the bush icon) to turn them off (Counterintuitive. Other clicks on objects only turn something on. You would think that clicking on the bush icon would turn the bushes off. Pam Murray is having trouble turning off the bushes: “I was clicking on the bush icon vs the bushes themselves. You’ll need to be specific. “)
- Click on rightmost white arrow to animate cyclist riding around the back of car in driveway and head-on into truck.
- To return to crash-type menu screen, click on orange x button in upper right corner. (not the orange button below the animation, which would close it).
- Now click on car (#2) for crashes with left-turning vehicles.
- Click on leftmost white arrow to run the animation.
- Click on the car to show the driver’s focus area. Driver is looking into gap, picks up speed, bicyclist is screened by car and truck in nearer lanes till they pass.
- Click on bicyclist to show bicyclist’s scan area. Bicyclist needs to look for car about to turn, and back for gap and right hook.

- Click the left arrow to the right of the car to show where the driver would be looking to the right if turning left – not looking at the cyclist.
- Click the x next to the arrows at the lower left to turn off the driver’s scan areas. (Keri’s narration in the video is out of sequence.)
- Click the cyclist to show the cyclist’s scan areas.
- Click the left white arrow twice to bring up the animation for the cyclist riding with traffic.

- Click on the orange x under the animation (not the one at the upper right) to close it.
